Huge energy efficient LED wall in China

Built specifically for the 2008 Summer Olympics, the 20,000 square foot wall of computer controlled LEDs will be completed in June. You may think that this is just your normal everyday 20,000 square foot LED wall, it is in fact powered completely from solar energy. errr... wait a minute this is the ONLY 20,000 square foot wall of LEDs so it being solar powered is just another notch on the designers belt. Anyone going to the 2008 Summer Olympics will be greeted by this beast and I'm sure anyone going to Beijing withing the next 50 years will be greeted by it as well.
